--- Comment #1 from Joseph S. Myers <jsm28 at gcc dot gnu.org> --- Author: jsm28 Date: Fri Oct 4 16:08:06 2019 New Revision: 276588 URL: https://gcc.gnu.org/viewcvs?rev=276588&root=gcc&view=rev Log: Mark C2x built-in functions as such. Various built-in functions that GCC has as extensions are now standard functions in C2x. This patch adds DEF_C2X_BUILTIN and uses it to mark them as such. Some of the so-marked functions were previously DEF_EXT_LIB_BUILTIN, while some DFP ones were DEF_GCC_BUILTIN (i.e. __builtin_* only); both sets become DEF_C2X_BUILTIN. This in turn requires flag_isoc2x to be defined in various front ends using builtins.def. As the semantics of the built-in functions should already be tested, the tests added only verify that they are declared in C2x mode but not in C11 mode. The test of DFP built-in functions being declared for C2x goes in gcc.dg/dfp/, as while such built-in functions currently don't depend on whether DFP is supported, that looks like a bug to me (see bug 91985), so it seems best for the tests not to depend on exactly how that bug might be fixed. Bootstrapped with no regressions on x86_64-pc-linux-gnu. gcc: * builtins.def (DEF_C2X_BUILTIN): New macro. (exp10, exp10f, exp10l, fabsd32, fabsd64, fabsd128, nand32) (nand64, nand128, roundeven, roundevenf, roundevenl, strdup) (strndup): Use DEF_C2X_BUILTIN. * coretypes.h (enum function_class): Add function_c2x_misc. gcc/ada: * gcc-interface/utils.c (flag_isoc2x): New variable. gcc/brig: * brig-lang.c (flag_isoc2x): New variable. gcc/lto: * lto-lang.c (flag_isoc2x): New variable. gcc/testsuite: * gcc.dg/c11-builtins-1.c, gcc.dg/c2x-builtins-1.c, gcc.dg/dfp/c2x-builtins-dfp-1.c: New tests.
